No complaints so far/ product review

I installed this on a 2019 WRX. I was a bit unsure how loud it would be, hard to determine that just based on audio found on the internet, However, I've been driving this around for 2 weeks now, its (relatively) quite when idling and cruising, but loud enough when you are stepping on it or even simply accelerating. I daily this car and am very happy with the volume. In my opinion, the exhaust note is also very good.

Install for this product was easy, the only "difficult" thing about the install was removing the OEM components. The fitment was good, when it came to the "muffler delete" components, I was expecting the new hangers to fall in place right where the original muffler hangers were. They did not, so I simply rotated the rubber hanger holders to adjust for the alternate position of the pipes. It's not a bid deal, but I was concerned about overstretching those rubber hangers; not sure what the complications will be down the road ( i.e. hangar failures that would drop the exhaust )

It had a few different burning smell for a bit, but it has since dissipated. I would attribute that to the normal chemical residues left by manufacturing. All in all, A+ exhaust system

Unleash the Rumble!

Great quality product, makes my STI sounds great! Quite loud obviously as it has no mufflers, but I didn't find it too loud for me anyways, cops aren't a huge issue where I'm normally driving. Some of the bandclamp connections needed a little trial and error to avoid exhaust leaks, but I liked having a bit of play in the connections for fitment.

Polished tips look great and clean up pretty well, the welds seem strong and the stainless steel seems high quality. It bolted right to my stock downpipe, and then to my Cobb one when I upgraded.
